Auto generate DSL on Scala

You can create APIs that resemble DSLs in Scala using method chains, implicits, and other syntactic sugar. For example, ScalaTest provides an API which is similar to natural languages and ScalikeJDBC leverages method chains to provide SQL-like syntax for its API. However, it is often very difficult to provide such sophisticated APIs.

Therefore, we developed a tool which automatically generates an API from your desired DSL grammars. This tool allows you to easily generate APIs which look like natural languages, or APIs similar to other existing DSLs in Scala. Internally, this tool takes advantage of Scala’s type checking system and implements a LALR parser. This session will introduce the tool itself and discuss how to implement it.
